[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Anderson Briglia <anderson.briglia@xxxxxxxxxxxxx>

Start SMP procedure for LE connections. This modification intercepts
l2cap received frames and call proper SMP functions to start the SMP
procedure. By now, no keys are being used.
